Abstract

L'invention concerne un dispositif de lecture pour un tringle capable de lire de manière plus fiable des étiquettes RFID de multiples articles vestimentaires suspendus sur un tringle. Le dispositif de lecture pour un tringle de la présente invention est destiné à un support de cintre pourvu d'un tringle pour suspendre de multiples cintres sur celui-ci. Le dispositif de lecture comporte : une partie de montage destinée à être suspendue sur le tringle d'une manière pouvant être montée/démontée librement ; une partie de corps reliée à la partie de montage ; une antenne dipôle pour communiquer avec des étiquettes RFID fixées à des articles de vêtements suspendus sur des cintres ; et un module de lecture disposé dans la partie de corps, connecté électriquement à l'antenne dipôle, et utilisée pour lire des informations à partir d'une étiquette RFID par l'intermédiaire de l'antenne dipôle. L'antenne dipôle est disposée de manière à s'étendre dans un plan croisant la direction d'extension du tringle lorsque la partie de montage est suspendue sur le tringle.
